BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to an improvement in an air disinfectionapparatus, and more particularly to an improved apparatus for thedisruption of power to a source of radiation, typically a radiation lampthat generates ultraviolet light, when the active radiation source isremoved from a confined space, for example, a HVAC (“heating/ventilationair conditioning”) duct. The invention further relates to an airdisinfection module that incorporates such an apparatus within a HVAC,and a method for guaranteeing disruption of power to a radiation sourcewhen the active radiation source is removed from a confined space.

2. Related Art

Germicidal lamps that generate ultraviolet light are now being used inHVAC duct systems for the disinfection of bacteria transported with theair. The germicidal or ultraviolet (hereinafter “UV”) lamps employed inHVAC ducts are generally powered by a source of electricity commonlylocated externally of the duct. The removal of the lamp(s) from the HVACduct, however, presents a safety problem in that the UV lamp's power maynot be discontinued during its removal, e.g., by disconnecting a plugfrom a wall socket or by disconnecting the lamp's electrical connectionwith a ballast. The prolonged exposure to the ultraviolet radiationemitted from the lamp, along with the lamp's intensity, may causeserious injury to the eyes or touch if precautions are not taken to shutthe lamp down before its handling or removal from the HVAC duct. Inaddition, the efficiency for generating ultraviolet light by a UVradiation lamp varies widely depending on the operating environment thatthe lamp is subject to, e.g., the temperature variations in a HVAC ductdue to the cooling of the air passing through the duct during the warmermonths of the year, and heated duct air during the winter months. Ittherefore becomes desirable to provide a safety mechanism that assuresthe disconnection of a radiation lamp before its removal from a duct. Itis also desirable to maintain an operating environment for the lamp thatwill enable it to perform at peak efficiency with maximum longevity.

An apparatus for sterilizing air using ultraviolet radiation emittingprobes inserted into an air duct is generally described in U.S. Pat. No.5,742,063 issued to Scroggins et al. on 21 Apr. 1998. Various lampsocket configurations have also been disclosed in the prior art. Forexample, FIGS. 5 and 6 of U.S. Pat. No. 2,472,977 issued to Mageoch etal. on 14 Jun. 1949, disclose a fluorescent lamp socket formed of a bodymember 13 that has a cylindrical recess 18 and a collar 29 that fitsover an opening 35 within a supporting panel 36 of a fluorescent lightfixture. The body member 13 has external mounting flanges 15 formounting to collar 29 and panel 36. In order to insure proper registryof body member 13 and collar 29, the collar is provided with an axiallyextending cup-shaped projection 31 adapted to nest in the annular seat17 of the cylindrical recess 18 of body member 13. The body member 13and collar 29 are permanently secured to the supporting panel 36 byrivets 32.

Each receptacle has an opening 34 forreceiving a transfer cable 50 containing wires 53 which are connected topins 26 on base 22 of lighting element 24. A grounded power supply plug40 with cord 42 is used to provide power to the sterilization device 10via a ballast. Power is transferred from the ballast through transfercables 46 to transfer cables 50 of the receptacle 30. FIG. 6 of U.S.Pat.

SUMMARY OF THE INVENTION

In accordance with a broad aspect of the invention, an air disinfectionassembly is provided comprising a radiation module for incorporationwith a conduit containing the passage of a fluid, typically air,therethrough. The module comprises a radiation lamp for generatingultraviolet light that includes a lamp base which supports (i) at leastone lamp tubing at one end thereof, (ii) a plurality of axiallyextending terminal pins, typically four, and (iii) a retention member.The retention member is typically a flange that is disposed about atleast a portion of the circumference of the lamp base.

In addition to the radiation lamp, the module additionally comprises apower disruption apparatus that includes a mounting member, preferablyhaving a flat plate-like construction, provided with an opening thatreceives the lamp tubing of the radiation lamp therethrough. The openingin the mounting member is configured in size to enable the retentionmember of the lamp base to restrict its axial movement beyond themounting member. This prevents the radiation lamp from falling into theinterior of a conduit, such as an HVAC duct, when the power disruptionapparatus is mounted to the conduit, typically with a fastening meanssuch as screws, threaded bolts, etc.

A coupling member is also provided which is mounted to the mountingmember for detachably securing the lamp base to the mounting member. Thecoupling member preferably comprises an annular collar whose annularopening is configured for receiving therein the lamp base that supportsthe terminal pins. The annular collar is also provided with fasteningmeans, e.g., screws, threaded bolts, or any other conventionalattachment means, for detachably securing the collar to the mountingmember about the lamp base. This arrangement allows the mounting memberand radiation lamp to be incorporated with the conduit, the latterhaving its lamp tubing extending into the interior of the conduit in adirection that is usually transverse to the flow of fluid passingtherethrough.

The power disruption apparatus also includes an electrical couplingmember, e.g., an electrical socket that includes electrical receptacles,for receiving the terminal pins of the lamp base. The electricalcoupling member is configured to detachably mount to the coupling memberin a manner that prevents detachment of the collar member from themounting member without the prior decoupling of the electrical couplingmember from the electrical terminal pins of the lamp base. In oneembodiment, the electrical coupling means may be configured in the formof a female electrical socket that not only connects with and receivesthe terminal pins of the lamp base, but also obstructs access to thefastening means which detachably secures the coupling member to themounting member. In this manner, withdrawal of the radiation lamp fromthe conduit interior or removal of the coupling member from the mountingmember can only be undertaken if the electrical coupling member, e.g.,the electrical socket, is disconnected from the radiation lamp. This hasthe effect of disrupting total electrical power to the lamp and avoidsthe harmful effects of exposure to the radiation generated by the lampwhen it is powered. In another embodiment, the electrical socket mayalso include an obstruction member that obstructs access to thefastening means of the annular collar when the socket is connected tothe terminal pins of the radiation lamp. The obstruction member may takethe form of extension members laterally extending from the socket whichobstruct access to the fastening means of the annular collar member whenthe socket is electrically engaged with the terminal pins of theradiation lamp. In yet another embodiment of the invention, theobstruction member may take the form of an annular obstruction memberdisposed between the socket and the annular collar for preventing accessto the fastening means of the annular collar.

The retention member, mounting member and collar member elementsdescribed above may be integrated into a unitary structure by disposinga mounting member about the end of the lamp base which supports theterminal pins. The mounting member is sized for detachable securement tothe conduit with a fastening means, such as one or more threadedfasteners, which has the effect of restricting the axial movement of thelamp base into the interior of the conduit. As a preference, themounting member is integral with the lamp base. The electrical couplingmember is detachably mounted to this mounting member for electricalengagement with the terminal pins of the lamp base in a manner thatprevents detachment of the mounting member from the conduit withoutprior detachment of the electrical coupling member from the terminalpins of the radiation lamp. As with the power disruption apparatusdescribed above, the electrical coupling member preferably comprises anelectrical socket that includes electrical receptacles for receiving theterminal pins of the lamp base, and is configured to obstruct access tothe fastening means of the mounting member when the electrical socket ismounted to said mounting member. The radiation module may optionallyinclude a radiation pervious protective sleeve which is configured toencompass the radiation lamp. The protective sleeve is closed at one endand open at the opposite end for slidable mounting to the radiationlamp. The open end of the protective sleeve, which is preferablyconstructed of fused quartz, is secured about the lamp base of theradiation lamp, directly to the mounting member itself, or both.

In accordance with another aspect of the invention, the radiation lampmay also embody a lamp base that supports two or more lamp tubings atone end thereof. The lamp base, which is common to one end of theplurality of lamp tubings, includes a plurality of axially extendingterminal pins, preferably two or four. In addition to the multiple tuberadiation lamp, the radiation module also includes (i) a mounting memberprovided with an opening for receiving the lamp tubings therethrough;(ii) a retention member, preferably a flange means, for restricting theaxial passage of the lamp base through the opening of the mountingmember; (iii) a locking member disposed about the opening for detachablysecuring the lamp base to the mounting member, preferably one or moreresilient clasps for detachable engagement with the lamp base; (iv) anelectrical coupling member, e.g., an electrical socket, for electricalengagement with the terminal pins; and optionally, (v) electrictransmission means connected to the electrical coupling member and atleast one ballast for powering the radiation lamp. The electricalcoupling member, e.g., an electrical socket that includes receptaclesfor receiving the terminal pins axially extending from the lamp base, isdetachably secured to the mounting member in a manner that preventsdetachment therefrom without prior disengagement of the electricalcoupling member from the terminal pins of the lamp base.

The electrical socket preferably comprises an obstruction member thatdetachably mounts to the mounting member about the locking member in away that prevents access to the locking member. The obstruction membermay be configured as an extension disposed about at least a portion ofthe perimeter of the electrical socket. In this embodiment, theextension is provided with fastening means that detachably secures theelectrical socket to the mounting member. More specifically, theextension may take the form of a lip disposed about the perimeter of theelectrical socket. The lip is preferably configured to interface withthe mounting member about the locking member, and is provided with atleast one opening to accommodate the insertion of the fastening meansfor the detachable securement of the electrical socket to the mountingmember.

The power disruption apparatus and/or radiation modules according to theinvention may optionally include electric transmission means, e.g.cabling or wiring, connected to the electrical coupling member and to atleast one ballast for powering the radiation lamp.

DETAILED DESCRIPTION OF THE INVENTION AND PREFERRED EMBODIMENTS THEREOF

Throughout the following description, the preferred embodiments andexamples are intended as exemplars rather than limitations on theapparatus, module and/or methods of the invention described below.

The present invention provides an improved apparatus and method for thedisruption of power to a radiation source, e.g., a germicidal lamp suchas an ultraviolet [hereinafter “UV”] lamp, when the radiation source isremoved from a confined space or passageway, or designated area ofoperation, e.g., an HVAC duct or conduit. Such an apparatus and methodassures the disruption of power to the UV lamp when the lamp is removedfrom its HVAC duct thereby avoiding exposure to the lamp's harmfulradiation effects while the lamp is in operation. In accordance with theinvention, a radiation module is provided that comprises a radiationsource coupled with an apparatus for the disruption of power to theradiation source upon the radiation source's removal from its designatedvicinity of operation.

Referring to FIG. 1, a radiation module 10 for the treatment of airpassing through a confined space, such as HVAC duct 12, is illustratedwherein, in one embodiment of the invention, radiation module 10comprises a radiation source such as UV lamp 14, a mounting means in theform of, for example, mounting plate 16, a lamp fastening means, e.g., acoupling member in the form of compression nut 22, and an electricalreceptacle means such as an electrical coupling member in the form ofsocket 20. A protective covering means, e.g., a dielectric boot 18 madeof, for example, rubber (see FIG. 2), may optionally be added to themodule, in which case boot 18 has an opening 19 in the top centralcovering portion thereof to facilitate the passage of an optionalelectrical conductor, e.g., electrical transmission cable 21, fromsocket 20 to an electrical power supply, e.g., a ballast 23 (see FIG.10), which in turn is connected to a source of power external of module10 via electrical plug 53.

As best illustrated in FIGS. 6 and 7, UV lamp 14 is in the form of afluorescent type lamp capable of emitting ultraviolet light at awavelength that includes 254 nanometers, although it may also include187 nanometers, the latter resulting in the creation of ozone. The UVlamp illustrated in greater detail in FIG. 6 is a conventional 4-pinlamp whose terminal pins 17,17 a are supported at one end by lamp base15. UV lamp 14 includes an elongate quartz tubing 14 a supported at eachend by lamp bases 15 and 15 a Quartz tubing 14 a is sealed at both ends6 and 7 which contain respective electrodes 8 and 9. The ends ofelectrode 6 are electrically coupled via appropriate conductor wires 6a,6 b with a pair of terminal pins 17 a, respectively, axially extendingfrom lamp base 15. The ends of the opposite electrode 7 are electricallycoupled with conductor wires 7 a,7 b which extend exteriorly of quartztubing 14 a and are connected to a pair of terminal pins 17 also axiallyextending from lamp base 15. A retaining ring 5 constructed of Teflon®is disposed about the mid section of quartz tubing 14 a to containconductor wires 7 a,7 b along the length thereof. While the lampillustrated in the figured drawings is a quartz (“hard glass”) four-pinUV lamp adapted for electrical connection to a power source, it will beappreciated that other types of terminal pins, numbers of terminal pins,e.g., two or more pins disposed at one end of the lamp, plugs and/orelectrical connectors may be employed with the UV lamp that areadaptable for coupling directly or indirectly to a power source. As anexample, in place of a “hard glass” lamp, a two- or four-pin “softglass” UV lamp manufactured by the Phillips Corporation may be usedwhich has a tubing that is permeable to ultraviolet light in thewavelength range that includes 254 nanometers.

The lamps commonly used in radiation module 10 are those that providelight transmission anywhere within the ultraviolet spectrum of light,i.e., within a light transmission range of approximately 150 to 400nanometers. Ultraviolet lamps typically used are low pressure mercurylamps, although any lamp producing an ultraviolet light sufficient tohave a destructive effect on germicidal activity, can be utilized. Forexample, high output, low pressure lamps may be used for the treatmentof air in the HVAC duct. These lamps generally contain a thicker lampfilament in the lamp's electrodes to absorb higher current settings forthe lamp's operation. If the lamp is able to operate at an increasedtemperature range, the deleterious effects of cooling air in the HVACduct is avoided. Normally, as cooling air moves past the outside surfaceof the lamp tubing, the operating temperature of the lamp will belowered thereby leading to a drop in the lamp's mercury pressure. As themercury vapor pressure is lowered, ultraviolet output activity of thelamp can be significantly reduced which may also lead to premature agingof the lamp.

Lamps commonly known as “splice lamps” may also be used. These lamps,which can be high output/low pressure or low pressure lamps, comprisetwo different types of glass tubing, e.g., a first and second glasstubing, typically fused together end to end in the axial direction ofthe lamp. When the lamp is activated, the first glass tubing willgenerate ultraviolet light in the radiation wavelength range that willproduce ozone, e.g., a range that includes a radiation wavelength of 185nanometers and 254 nanometers. A second glass tubing of the “splicelamp” will generate ultraviolet light in a radiation wavelength rangethat includes 254 nanometers without the generation of any substantialamounts of ozone.

“Twin tube” lamps whose tubes are in a U-shaped configuration andmounted to a common lamp base for connection to a source of electricalpower, may also be employed in the module according to the inventionherein. Alternatively, the tubes may be aligned in a parallel fashionrelative to each other and joined at the ends by a “cross-over” sectionof tubing. As shown in FIG. 13, the opposite ends are also mounted to acommon lamp base.

Other lamps include medium pressure ultraviolet lamps as well ascapacitor discharge lamps that utilize pulse technology wherein aluminous output arises from the ionization in a gaseous discharge,examples of which include xenon lamps.

As best illustrated in FIGS. 2, 4, 4A, and 9, and in accordance with oneaspect of the invention, module 10, in addition to UV lamp 14, comprisesa power disruption apparatus 11 for the disruption of power to the lampthat includes a mounting means in the form of mounting plate 16 that ismountable with the exterior surface 24 of duct 12 about duct opening 25.Mounting plate 16 is provided with an opening 27 for registry with ductopening 25 in order to accommodate the passage of UV lamp 14therethrough into the interior of duct 12. Also provided are mountingapertures 29 for the insertion of fastening members which may take anyform for the attachment of mounting plate 16 to the exterior surface 24of duct 12, e.g., sheet metal screws 31 as shown, bolts, rivets, etc. Asbest shown in FIG. 9, mounting plate 16 additionally includes a pair ofinternally threaded bosses 33 mounted to the top side 34 of mountingplate 16 adjacent to opening 27 to receive correspondingly threadedfasteners in the form of threaded bolts 35 for attaching compression nut22 (described below) to mounting plate 16 (see FIGS. 2, 4, 4A, 8 and 9).

Referring now to FIGS. 4, 4A and 8, and more specifically to FIG. 8, acoupling member in the form of an annular compression nut 22 is providedwhose annular opening 37 is sized to accommodate the receipttherethrough of the top portion 15 b of lamp base 15. The lower annularwall 39 of compression nut 22 is undercut to provide an annular seat 41that interfaces with a retention member in the form of flange 28 at thetop side 26 thereof (see FIG. 7). Flange 28 is disposed about andsecured to the exterior mid-section of lamp base 15 of UV lamp 14.Referring to FIGS. 5 and 9, apertures 33 a are provided in flange 28 toaccommodate the receipt therethrough of bosses 33 when UV lamp 14 isinserted through opening 27 of mounting plate 16 and the bottom surface30 of flange 28 comes to rest upon and interfaces with the top surface34 of mounting plate 16. This arrangement maintains lamp base 15 (aswell as UV lamp 14) in a stationary position relative to exteriorsurface 24 of duct 12, and prevents UV lamp 14 from falling into theinterior of duct 12.

Compression nut 22 is provided with fastener openings 43 for theinsertion of fastening means for the securement of the nut to mountingplate 16. The height h of compression nut 22 (see FIG. 8) is sized suchthat when it is placed over lamp base 15 of UV lamp 14 and secured tomounting plate 16 using a fastening means, e.g., threaded bolts 35,terminal pins 17,17 a of UV lamp 14 will extend beyond the top planarsurface 44 of compression nut 22 (see FIGS. 4 and 4A) sufficiently toexpose terminal pins 17,17 a for engagement with correspondingelectrical receptacles (not shown) contained within socket 20 (see FIGS.4 and 11).

Referring now to FIGS. 4, 4A and 11, the apparatus also includes anelectrical coupling means that connects UV lamp 14 with an electricalpower supply, e.g., a ballast 23 (see FIG. 10), for the lamp'soperation. The electrical coupling means may, for example, take the formof an electrical coupling member comprising a socket 20 having anelongate section 48 that has a front end 50 and an opposite tapered end52 (see FIGS. 4 and 11). Embedded within socket 20 about the front end50 are four electrical receptacles (not shown) about end 50 thatinterface with and receive with a resistance fit the terminal pins 17,17a axially extending from the top portion 15 b of lamp base 15. Theopposite end 52 is provided with four openings 46 for receiving twopairs of electrical transmission wires 49 and 51 which are secured atone end thereof to the respective electrical receptacles within socket20 that receive terminal pins 17,17 a. For convenience, electricaltransmission wires 49,51 are carried within cable 21. As shown in FIG.10, the opposite ends of electrical transmission wires 49,51 areelectrically connected via cable 21 to ballast 23. It will beappreciated that the electrical receptacles embedded within socket 20can be extended over the length of elongate section 48 to interface backend 52 of socket 20 to provide a female-to-female socket. In thisembodiment the electrical receptacles (not shown) may be adapted tointerface with and receive with a resistance fit the electrical pins ofa mateable male plug (not shown), the latter being electricallyconnected to ballast 23 via electrical transmission cable 21.

As illustrated in FIG. 11, the electrical coupling member is alsoconfigured in a manner to obstruct access to the fasteners thatdetachably secure compression nut 22 to mounting plate 16. Accordingly,an obstruction element is provided for the electrical coupling member,in this case side extensions 54 disposed on opposite sides of elongatesection 48 about end 50, for overlying the heads of threaded bolts 35.The primary function of side extensions 54 is to prevent access to thefastening means, i.e., threaded bolts 35, which detachably securecompression nut 22 to mounting plate 16. As a secondary function, sideextensions 54 may optionally be provided with openings 56 (FIGS. 4 and4A) to receive fastening means in the form of threaded fasteners 55 foradditional detachable securement of socket 20 with compression nut 22.As shown in FIG. 8, threaded fasteners 55 may be in the form of screwsor threaded bolts which are inserted through openings 56 for engagementwith aligned openings 58 (see FIG. 4A) of compression nut 22. It will beappreciated that socket 20 may be configured in any manner that providesan electrical connection with terminal pins 17,17 a of UV lamp 14 whilesimultaneously preventing access to the fastener, e.g., threaded bolts35, which detachably secures compression nut 22 with mounting plate 16.

As an alternative to side extensions 54, and as shown in FIG. 12, aproperly configured annular member 57 may be interposed betweencompression nut 22 and socket 20 in order to prevent access to threadedbolts 35 which secure compression nut 22 to mounting member 16. In thisembodiment, the annular opening 59 of annular member 57 is sized suchthat the exposed portion of terminal pins 17,17 a will have fullpenetration into the corresponding receptacles at end 50 of socket 20.

As an alternative to the configuration of socket 20 in the foregoingapparatus and module, FIG. 12 illustrates another embodiment for anelectrical coupling member. Referring to FIG. 12A, the electricalcoupling 70 comprises an electrical socket 74 that retains a pair ofelectrical receptacles 75,76 the ends of which are connected withelectrical transmission wires 49,51 (see FIG. 11) carried by cable 21.The opposite open ends of electrical receptacles 75,76 are disposedwithin the socket for receiving terminal pins 17,17 a of lamp base 15with a resistance fit. Mounted about socket 74 is a freely rotatinghousing 73 that includes an exteriorly threaded, annular extension 71and a non-threaded extension 73 a axially extending from either side ofa flange 72. The housing 73 is mounted about socket 74 and the endportion of cable 21 such that it is free to rotate about cable 21 andsocket 74, but is axially fixed to cable 21 about the end thereof.Extension 71 is configured for threaded engagement with thecorrespondingly threaded annular interior 22 a of compression nut 22shown in FIG. 12.

Assembly of electrical coupling 70 with UV lamp 14 is as follows. Aftercompression nut 22 is placed over top portion 15 b of lamp base 15 andsecured to mounting plate 16 by the insertion of threaded bolts 35through openings 43, annular member 57 is placed over the annular planarsurface 38 of compression nut 22 to prevent access to threaded bolts 35.The electrical receptacles 75,76 of socket 74 contained withinelectrical coupling member 70 is then mated with terminal pins 17,17 asimultaneously with the insertion of extension 71 through the annularopening 59 of annular member 57. Flange 72 is rotated for threadedengagement of threaded extension 71 with the interior of compression nut22 to complete the connection.

Assembly of the radiation module 10 illustrated in FIG. 4 and itsincorporation with duct 12 to provide an air disinfection assembly, isaccomplished by securing mounting plate 16 to duct 12 in a manner thatthe opening 27 in mounting plate 16 (see FIG. 9) and the opening 25 ofduct 12 (see FIG. 10) are in direct alignment with each other. Lamp base15 a of UV lamp 14 is then inserted through openings 27 and 25 to apoint where the bottom surface 30 of flange 28 interfaces with the topsurface 34 of mounting plate 16. Once UV lamp 14 is in place,compression nut 22 is fitted over the extended top portion 15 b of lampbase 15 and the compression nut attached to mounting plate 16 by afastening means, in this case by the engagement of threaded bolts 35with bosses 33 as shown in FIG. 9. Stationary securement of UV lamp 14with duct 12 is thereby obtained. UV lamp 14 is coupled with a source ofelectrical power by aligning the electrical receptacles of socket 20over pins 17,17 a of the top portion 15 b of lamp base 15 for insertionof the pins therein. As illustrated in FIGS. 10-11, electricaltransmission wires 49 and 51, which connect with the respectiveelectrical receptacles within socket 20, are electrically connected viacable 21 to ballast 23 to complete the incorporation of radiation module10 with HVAC duct 12.

With the foregoing power disruption apparatus integrated with UV lamp 14and HVAC duct 12, removal of UV lamp 14 from duct 12 can only beachieved by the disruption of electrical power to the lamp. Accordingly,when circumstances warrant the removal of UV lamp 14 from duct 12, e.g.,for cleaning the lamp's surface or simply to replace the lamp, socket 20must first be disconnected from compression nut 22. This is accomplishedby either removing the threaded fasteners 55 (see FIG. 8) from therespective side extensions 54 of socket 20 (FIG. 4A), or if the threadedbolts 55 are not utilized as in FIG. 11, by simply uncoupling the socket20 from the terminal pins 17,17 a of UV lamp 14. Once removed, threadedbolts 35, which secure compression nut 22 to mounting plate 16, will beaccessible for their removal from the compression nut 22 and the bosses33 of mounting plate 16. As a consequence of the foregoing process, thepower to UV lamp 14 is totally disrupted before its removal from HVACduct 12, and compression nut 22 can be lifted off the top portion 15 bof lamp base 15 and the lamp safely withdrawn. The lamp's withdrawalfrom duct 12 can only be accomplished by decoupling socket 20 from theterminal pins 17,17 a of UV lamp 14.

In accordance with another aspect of the invention, FIGS. 10-11 show amodified power disruption apparatus and radiation module. It will beappreciated that all parts illustrated in FIGS. 10 and 11 and thoseFigures that follow, which are identical with or clearly analogous tothe corresponding part of the apparatus and module shown in FIGS. 1-9,are denoted by like reference numerals and characters.

Referring to FIG. 10, radiation module 60 is comprised of a radiationsource, e.g., in the form of UV lamp 62, an electrical coupling member,e.g., socket 20, and a mounting member 64 for securing one end of UVlamp 62, i.e., the end carrying terminal pins 17,17 a, to the surface 24of duct 12. As shown in greater detail in FIG. 18, reference numeral 62designates a low pressure ultraviolet radiation lamp comprising avacuumed tubular portion 14 a that is sealed at each end thereof in thesame manner illustrated in FIG. 6. Both tubular ends 6 and 7 of UV lamp62 are retained and supported by lamp bases 15 and 15 a, respectively.Secured about the end portion of lamp base 15, and made integraltherewith, is a mounting member 64 of ceramic or plastic constructionwhose cross-sectional area is configured to be sufficiently larger thanduct opening 25 so as to maintain the mounting member exteriorly of duct12 when UV lamp 62 is inserted into the duct interior via opening 25.Lamp base 15 can be made integral with mounting member 64 in any numberof ways, for example by providing a bore within the mounting member fordefining a seat that the end of lamp base 15 butts against when insertedinto the mounting member. The bore within mounting member 64 isaccompanied by axially extending apertures through the mounting memberfor exposure of the terminal pins 17,17 a beyond the member's planarsurface 65 (see FIG. 11). Alternatively, mounting member 64 can beconfigured as an annular element whose annular opening is sized toslidably receive lamp base 15 therein. In either configuration, lampbase 15 may be retained within mounting member 64 by the application ofan appropriate fixative or sealant, e.g., an ultraviolet light curativeepoxy cement available from Norland Products Inc. under the name ofNorland Electronic Adhesive, between the mounting member's bore orinside annular surface, as the case may be, and the outside surface oflamp base 15. Mounting member 64 and lamp base 15 can also be configuredinto a single or unitary structure for carrying the terminal pins 17,17b to support the end 6 (see FIG. 6) of lamp tubing 14 a whilefunctioning as a flange relative to surface 24 of duct 12. Whilemounting member 64 is illustrated in FIGS. 11 and 18 as having acircular cross-section, it may be configured in any shape or form to actas an interface with the exterior surface 24 of duct 12, typically inthe form of a flange.

The mounting member 64 of lamp base includes a plurality of apertures(not shown) to accommodate the insertion of terminal pins 17,17 aemanating from lamp base 15, the terminal pins extending in the axialdirection beyond the planar surface 65 of mounting member 64 foravailable electrical connection with female-to-female socket 20. Alsoincluded within mounting member 64 are a pair of countersunk fasteneropenings 66 to accommodate the insertion of threaded bolts 35 thereinfor securing mounting member 64 to the surface 24 of duct 12 aboutopening 25. The integration of mounting member 64 with lamp base 15,terminal pins 17,17 a and the remainder of lamp 62, provides asimplified and economical means for incorporating UV lamp 62 with duct12. Alternatively, it will be appreciated that mounting member 64 may beannularly configured and secured about the end of lamp base 15, i.e.,the end portion of lamp base 15 will be inserted into an annular openingof the mounting member and secured therewith by any conventional means.

As shown in FIG. 10, once lamp base 15 a of UV lamp 62 is insertedthrough duct opening 25 to a point where the surface 68 of mountingmember 64 interfaces with the exterior surface 24 surrounding opening 25of duct 12, end 50 of socket 20 is fitted over the exposed terminal pins17,17 a of mounting member 64 for receiving them into the electricalreceptacles contained within the socket. Electrical transmission wires49,51 are electrically connected via cable 21 between the opposite endsof the electrical receptacles in socket 20 (via openings 46) and ballast23 to complete the electrical coupling of lamp 62 to the ballast. Aswith radiation module 10, and the apparatus illustrated in FIGS. 1-9 anddescribed hereinbefore, the side extensions 54 of socket 20 will coveropenings 66 and threaded bolts 35 already inserted into mounting member64. This arrangement prevents the removal of lamp 62 from duct 12 unlesssocket 20 is decoupled from pins 17,17 a of UV lamp 14. With thisembodiment of the invention, the functions of mounting plate 16,compression nut 22 and lamp base 15 of module 10 are integrated into aunitary structure.

FIGS. 13-16 illustrate yet another embodiment of the invention herein.Referring to FIG. 13, radiation module 80, like radiation modules 10 and60, comprises a “twin-tube” UV lamp 82 and a power disruption apparatus84. As shown in greater detail in FIG. 14, UV lamp 82 comprises twohollow elongate quartz tubes 86,87 that are parallel to each other alongtheir longitudinal lengths, and joined together about one end 88 of lamp82 by a short hollow connecting tube 90. The electrodes 92,93 of therespective tubes 86,87 are disposed at the opposite ends 95 of the lamptubes, and are connected respectively, via lead wires (not shown), withterminal pins 97,98 carried by and axially extending from a common lampbase 100.

Power disruption apparatus 84 comprises a mounting member 102 providedwith fastener openings 104 for securement of the member to the exteriorsurface 24 of duct 12 utilizing a fastening means, e.g., screws orthreaded bolts (not shown). As shown in greater detail in FIG. 15, acentrally positioned opening 106 provided in the mounting member isconfigured to receive quartz tubes 86,87 of UV lamp 82 therethrough (asshown in FIG. 16). It will be understood that when mounting member 102is attached to duct 12, opening 106 will register with a similar openingprovided in the wall of duct 12 (not shown) to receive UV lamp 82 intothe interior of the duct. As best shown in FIG. 15, the front side 108of mounting member 102 is undercut to provide a seat 110 that interfaceswith the back end 112 of lamp base 100 (see FIG. 14) for defining aflange for UV lamp 82 when it is inserted through mounting memberopening 106. In order to maintain the lamp in place, releaseable lockingmeans, e.g., resilient retainer clasps 114,115 which have a spring biasin a direction pointing to the center of opening 106, are disposed aboutthe perimeter of opening 106 on the front side 108 of mounting member102. As shown in FIG. 13, when UV lamp 82 is sufficiently inserted intoduct 12, the spring bias of retainer clasps 114,115 will exertthemselves against the front side 113 of lamp base 100 and lock the lampbase within opening 106 of mounting member 102. In this manner, one endof lamp base, i.e., end 112, serves as a lip that interfaces with seat110 of mounting member 102, and cooperates with the front or oppositeside 113 of lamp base 100 to provide a locking mechanism for securingthe lamp to duct 12.

In order to supply electrical power to UV lamp 82 from a source externalto module 80, and as illustrated in greater detail in FIG. 13, anelectrical coupling member, e.g., female socket assembly 117, isemployed as part of the power disruption apparatus 84. As best shown inFIGS. 13 and 13A, female socket assembly 117 comprises a socket 118having front and rear sides 121 and 122, respectively, the socket beingmade of ceramic, plastic or similar solid dielectric material, and beingoverlaid with an optional dielectric boot 131. Socket 118 is sized andconfigured to accommodate the containment of electrical receptacles124,125 that register with and receive terminal pins 97,98 of lamp 82,respectively, which project from lamp base 100. One end of electricalreceptacles 124,125 terminates at the planar surface of the casing'srear side 122, while their opposite ends are respectively connected withelectrical conductor wires 127 and 128 emanating from the front side 121of socket 118. The electrical conductor wires 127, 128 are collectivelyhoused in an insulated cable for connection to an electrical powersource. Disposed about the periphery of socket 118 is a joining memberin the form of a circumferential lip 134 that includes openings 136,137(FIG. 13A) for affixing female socket 118 to the front side 108 ofmounting member 102. Mounting apertures 139,140 are provided in mountingmember 102 for receiving attachment screws 142,143 therein throughopenings 136,137. Socket 118 additionally includes slotted indentations129,131 (FIG. 13A) to accommodate the receipt of resilient retainerclasps 114,115, respectively, when the rear side 122 of the socket isinterfaced with the front side 113 of lamp base 100.

Female socket assembly 117 may optionally include a dielectric boot 131made of a flexible insulating material that is sized and configured toreceive socket 118 therein. Boot 131 also includes an electricalinsulating cable 132 for receiving and carrying conductor wires 127,128to an electrical power source, e.g., ballast 23 which is illustrated inFIG. 10. Attached about or integral with the periphery of boot 131 is ajoining member in the form of a circumferential lip 134A that isconfigured to overlie circumferential lip 134 of socket 118.Circumferential lip 134A includes openings 136A,137A for registry withthe openings 136,137 in lip 134 (see FIG. 13A) to accommodate theinsertion of attachment screws 142,143 therethrough.

Assembly of radiation module 80 is best illustrated in FIGS. 13, 15 and16. Retainer clasps 114,115 are manually pushed in a direction away fromthe center of opening 106 of mounting member 102, and UV lamp 82simultaneously inserted into opening 106 until the back end 112 of lampbase 100 butts against seat 110 of mounting member 102. Thereafter,retainer clasps 114,115 are released to lock lamp base 100 withinmounting member 102. Electrical receptacles 124,125 of socket 118 arethen aligned and coupled with terminal pins 97,98, respectively, whichhas the effect of preventing access to retainer clasps 114,115 bycircumferential lip 134. As best seen in seen in FIG. 13, securement offemale socket assembly 117 and its boot 131 to the terminal pins 97,98of UV lamp 82, is insured by inserting attachment screws 142,143 throughthe respective openings 136 and 136A of circumferential lips 134 and134A, respectively, into the corresponding mounting appertures 139,140of mounting member 102.

With the assembly of radiation module 80 complete, the module may beincorporated with duct 12 by inserting lamp end 88 into the opening (notshown) of duct 12 and securing mounting member 102 thereto by the use offastening means, e.g., mounting screws (not shown), inserted intoopenings 104 and into the wall of duct 12. Alternatively, the assemblyof radiation module 80 can be undertaken simultaneously with itsincorporation with duct 12. Mounting member 102 may initially be fixedto duct 12 by registering opening 106 with the corresponding opening(not shown) provided in the duct wall, and then securing the mountingmember to the duct wall in the manner described above. Once mountingmember 102 is secured in its proper place with duct 12, the remainder ofmodule 80 is assembled by first inserting lamp end 88 into the ductinterior and locking the lamp base 100 with the mounting member viaretainer clasps 114,115. With the terminal pins 97,98 of UV lamp 82exposed, their connection with an electrical power source isaccomplished by coupling them with the appropriate electricalreceptacles 124,125 of female socket assembly 117, and then insulatingcable 132 with an electrical power supply, e.g., ballast 23 as shown inFIG. 10. As described above, securement of female socket assembly 117 tomounting member 102 is assured by the use of attachment screws 142,143inserted through the respective openings 136,136A of circumferentiallips 134,134A and into the corresponding mounting apertures 139,140 ofmounting member 102.

Referring now to FIG. 17, interchangeability of twin-tube UV lamp 82with, for example, a single tube lamp such as UV lamp 14 illustrated inFIGS. 2 and 6, is made possible by the incorporation of an adapter 145with mounting member 102. Adapter 145, which is configured in size andshape to fit within opening 106 of mounting member 102, itself containsan opening 147 for receiving UV lamp 14 therethrough. Once inserted, andas illustrated in FIG. 15, the back side (not shown) of adapter 145interfaces with and rests upon seat 110 (see FIG. 15) of mounting member102. Adapter 145 is held in place within mounting member 102 by theinsertion of UV lamp 14 into opening 147 whereupon the bottom surface 30of flange 28 (see FIGS. 2 and 7) will interface with the front side 149of adapter 145.

As shown in FIG. 13A, and in order to secure UV lamp 14 in place, theelectrical receptacles 46A,46B of female socket assembly 117 are thenfitted over terminal pins 17,17 a of the extended portion of lamp base15, and secured to mounting member 102 in the same manner as thatillustrated in FIGS. 13 and 16.

In another embodiment of the invention, the radiation modules describedherein include the incorporation of a radiation pervious protectivesleeve mounted about the radiation lamp to stabilize the operatingtemperature of the inner and outer portions of the lamp tubing when itis subjected to temperature fluctuations of the air being passed throughan HVAC duct. HVAC duct systems generally operate by admitting air froman outside environment and then subjecting it to filtration, coolingand/or heating, and humidification, and finally transporting it via aduct system to a plurality of rooms or spaces such as offices andliving, commercial and industrial spaces, or vehicles such asautomobiles and public transport vehicles, e.g., airplanes, buses,trains, etc. The longevity and efficiency of UV lamps used in HVACsystems are generally dependant upon the temperature of the duct airthat they are exposed to. UV lamps will operate at maximum efficiencywhen the temperature of the lamp's exterior tubular surface ismaintained at a range of from 103° F. to 110° F., with peak efficiencybeing obtained at approximately 105° F. Contributing factors toward thelamp's operational efficiency include a proper matching of the lamp witha ballast or power source, i.e., the electrical characteristics of thelamp and ballast should complement each other. For example, if the UVlamp is underpowered, the optimum 105° F. operating temperature may notbe achieved. If the UV lamp is overpowered, i.e., operated at anamperage beyond the recommended specification for the lamp in question,it will usually result in premature lamp failure or solorization of thelamp, thereby shortening the lamp's useful life. Solorization is theprocess by which UV lamps lose the ability to generate ultravioletenergy in the UVC radiation wavelength range over a period of time. Thisis due to the lamp's mercury becoming embedded into the interior of theglass tubing which leads to mercury loss and contributes to the UVlamp's inefficiency and shortened life span.

Another contributing factor is heat removal from the lamp's operation.This is borne out by the graph in FIG. 19 which charts the radiationenergy (in ultraviolet micro-watts per square centimeter, measured at adistance of one foot from the lamp) of a 4-pin, low pressure, industrystandard ultraviolet lamp [gph357t5/L] manufactured by First LightTechnologies Inc. of Poultney, Vermont. The UV lamp was positionedwithin an air duct and operated at duct air temperatures ranging from42° F. to 65° F. The graph demonstrates that as the duct air temperatureincreases, an increase in operating efficiency is experienced by the UVlamp in an amount of approximately 50 percent (see the lower linerepresentation in FIG. 19). This contrasts with the efficiencyexperienced by the UV lamp when a radiation pervious protective sleeve,typically constructed of fused quartz, is placed over the same lamp (asillustrated in FIG. 18) and subjected to the same operating conditions.The upper line shows more than an 80 percent increase in ultravioletmicro-watts at the lower end of the temperature range (42° F.) and aslight increase in micro-watt output when the air duct temperatures riseabove 57° F.

While not being bound to any specific theory or explanation, it isbelieved that the cooler duct air temperatures will lower the skintemperature of the lamp's tubing, and in turn, the inside operatingtemperature of the lamp. This lowering of temperature causes the mercuryvapor pressure inside the lamp to drop which leads to the production ofless ultraviolet light. Moreover, as heat is drawn away from the UV lampby the colder duct air, the operating longevity of the lamp sufferssignificantly.

Referring now to FIG. 18, UV lamp 62, which is the same as thatillustrated in FIG. 11, is enclosed by a radiation pervious protectivesleeve. The sleeve is typically constructed of fused quartz, althoughany of the ultraviolet pervious materials such as Kynar® or Teflon maybe used. Thus, quartz sleeve 63 has a closed dome-shaped configurationat one end 67 and is open at its opposite end 69. The open end 69 issized to slidably fit about the circumference of lamp base 15 andinterface with the back surface 68 of mounting member 64. Quartz sleeve63 is fixed in place by the application of an appropriate fixative orsealant, e.g., an ultraviolet light curative epoxy cement available fromNorland Products Inc. under the name of Norland Electronic Adhesive,between the inside surface of the sleeve's open end 69 and the outsidesurface of lamp base 15, between the open end 69 of the sleeve and theback surface 68 of the mounting member, or by an application to bothareas. Alternatively, and as described hereinbefore, mounting member 64may be provided with an axial bore the end of which defines a seat thatthe end of lamp base 15 butts against when the lamp is inserted into themounting member. In order to accommodate the inclusion of quartz sleeve63, the size of the bore may be configured such that both ends of lampbase 15 and quartz sleeve 63 are slidably received within the bore andfastened to the seat of the bore with the appropriate fixative.Alternatively, a “stepped bore” may be incorporated in mounting member64 to define a seat for the end of lamp base 15 and a separate higherseat for the open end 69 of quartz sleeve 63.

Quartz sleeve 63 may also be included with the other modular embodimentsdescribed hereinbefore. For example, referring to FIG. 7, the insideopen end 69 of quartz sleeve 63 may be slidably fitted onto lamp base 15and secured to the outer surface of the lamp base as well as the bottomsurface 30 of flange 28. A similar arrangement may be followed with thelamp base 15 and flange 28 illustrated in FIG. 12. And in FIG. 12, theopening 27 of mounting member 16 is sized to accommodate the receipttherethrough of quartz sleeve 63 surrounding and fixed to lamp base 15beneath flange 28. The incorporation of a quartz sleeve with a UV lampin accordance with the invention herein serves to balance thetemperature of the lamp, and by doing so, optimum performance, coupledwith increased longevity, is achieved.

Since other modifications and changes may be varied to fit theparticular operating requirements and environments of the invention,which will be apparent to those skilled in the art, the invention is notconsidered to be limited to the embodiments chosen for purposes ofdisclosure, and covers all changes and modifications which do notconstitute departures from the true spirit and scope thereof.
